  • Title: [Brain stem AEP in toxic comas. Correlation with brain stem reflexes].

    Abstract:
    24 deep toxic comas with respiratory assistance were studied by brain-stem reflex and BAEP. Laboratory analysis showed several simultaneous toxics (phenobarbital, benzodiazepines, tricyclic antidepressants...). Three groups of patients were defined: Twelve patients with normal BAEP and with relatively preserved brain-stem reflex (oculocephalic and oculovestibular are often disturbed but photomotor is present). Eleven patients with delayed BAEP and with more disturbed brain-stem reflex (photomotor is missing 3 times). In 2 cases (one of which is mentioned above in group B) brain-stem reflex and BAEP disappear and these patients die. Cerebral anoxia is associated here with toxics. Causes of delayed latencies (group B) are discussed (hypothermia, toxics). BAEP seems important in diagnosis and prognosis of toxic coma.
